摘要：

Cs,Rh-codoped WO3 showed photocatalytic activity for O-2 evolution from an aqueous Fe(ClO4)(3) solution under irradiation of light with a wavelength Longer than 500 nm, although the activities of nondoped, Rh-doped, and Cs-doped WO3 were negligible. The optimized WO3 codoped with Cs (5 mol%) and Rh (0.5 mol%) responded to visible Eight up to 600 nm. Moreover, the Cs,Rh-codoped WO3 was successfully applied as an O-2-evolving photocatalyst for Z-schematic water splitting into H-2 and O-2 stoichiometrically with a H-2-evolving photocatalyst and an Fe3+/2+ redox mediator under irradiation of Eight with a wavelength Longer than 500 nm.
